(8/24/2004, Denver, CO) Researchers have found evidence that nitrogen compounds from Front Range tailpipes, power plants, crop fields and feed lots has altered the subalpine forest and alpine tundra in the Rocky Mountain National Park's Loch Vale watershed. Each Tuesday, park technician Lisa Foster samples stream water, collects precipitation that falls on the Loch Vale experimental site, and downloads data for scientist Jill Baron, who works for the U.S. Geological Society. She is looking at data collected on the paper each time the level of the flume goes up and down - thus letting the scientists know how many times it rained, or an "event" occurred during the week.

After checking readings from the Loch Vale collection site, RMNP technician Lisa Foster downloads the data to the U.S. Geological Survey in Fort Collins. The data tell scientists how many times it has rained during the week at the site.
